Muhammad Samir Khan commented on HDFS-12491:
--------------------------------------------
testWildCard.sh uses following java code to test the output of the wildcard
classpath expansion in the patch vs the one done by java launcher:
{code:java}
public class PrintClasspath {
public static void main(String[] args) {
System.out.println(System.getProperty(\"java.class.path\"));
}
}{code}
The test cases are in the shell script. Can add more test cases as well.
> Support wildcard in CLASSPATH for libhdfs

> Issue Type: Improvement

> According to libhdfs doc, wildcard in CLASSPATH is not support:
> bq. The most common problem is the CLASSPATH is not set properly when calling
> a program that uses libhdfs. Make sure you set it to all the Hadoop jars
> needed to run Hadoop itself as well as the right configuration directory
> containing hdfs-site.xml. It is not valid to use wildcard syntax for
> specifying multiple jars. It may be useful to run hadoop classpath --glob or
> hadoop classpath --jar <path> to generate the correct classpath for your
> deployment.
